When the 39-year-old quarterback zeroed in on his target and decided it wasn't worth looking off any of the Calgary Stampeders defensive backs, Wall pounced, tipping the ball to himself in the middle of the field for his first interception of the season.

He was careful not to touch the Ottawa RedBlacks receiver.

Very careful.

The new rule that makes defensive pass interference a reviewable play is just seven weeks old, but many defensive backs are still viewing it the same way they did when it was first announced over the off-season -- it's not fair.

Through Week 7, head coaches around the CFL have thrown challenge flags 14 times on suspected pass interference plays.

Only two of those have been overturned -- both changing an incomplete pass into a pass interference penalty -- and they came in Week 1 and Week 2.
